Thanks to everyone for your replies. In the context of my personal needs regarding paramertrics:
When designing RTA plywood furniture for CNC routing, sheet thickness effects dimensions of mortise+tenon joints etc. Or when designing a ring (jewelry), it’s diameter is the variable in 3d print production - to account for the customer’s finger size, etc.
These are fairly basic examples and that’s all I’m looking for. I started out using Rhino in the furniture example, but encountered the need to vary the sheet thickness in my designs, hence me moving to Fusion 360. I am not familiar with Grasshopper, but if it can address both needs above then I’d be happy to switch back to Rhino/Grasshopper.
I am also considering getting a PC and dedicate that machine for my 3D design projects (I am a ux designer by trade and use a Mac for my business/work). I have been advised that this is the best way to go as Rhino for Windows provides more capabilities than Rhino for the Mac.
Currently I can run Rhino v5, but it says that my license is expired and cannot save. Screen shot attached.
Appreciate your feedback, thanks.
